Missoula is the home to Adventure Cycling Association (ACA). ACA is a nonprofit organization that promotes travel by bicycle for fitness, fun, and self-discovery. ACA researches and produces cycling maps for biking trail systems across the US. Come by and visit ACA headquarters at 150 East Pine Street.
ACA serves a worldwide membership of nearly 47,000 members, making it North America's premier bicycle-travel organization. ACA has more than 42,000 miles of mapped roads and trails making up the Adventure Cycling Route Network. These include three east-west cross-country routes, including the original TransAmerica Trail (which passes through the Bitterroot Valley and Missoula area); routes tracing both the East Coast and West Coast; an off-pavement mountain-bike route paralleling the Continental Divide from Canada to Mexicao; and many others. The newest, launched in February 2014, is the Idaho Hot Springs Mountain Bike Route, a glorious loop of 518 miles circling through the heart of central Idaho. On the drawing board and scheduled for completion in 2015 is the Bicycle Route 66, which traces the historic "Mother Road" from Chicago to Southern California.
In 2014, The Adventure Cycling Tours Department offers more than 60 different tours in the US and Canada (and more than 80 dates), ranging in duration from three days to three months. The level of support varies a great deal as well, from tours that are totally self-contained - on which riders carry all their bicycle and camping gear and cook their own meals - to fully van-supported and catered.
